PolyDryer Annealing Mod – Soften, Dry & Anneal Your Prints

This mod platform is designed to be placed inside the Polymaker PolyDryer, transforming it into a more versatile tool for makers. By elevating objects inside the chamber, it allows more efficient use of heat for post-processing and material treatment.

Key Features

Dual-chamber heat flow – thanks to the central wall, the inner space is divided into two sections. This directs the hot air upwards, ensuring faster heating with less heat loss.

Annealing – improve the strength and stability of your 3D printed parts by heat-treating them.

Softening & reshaping – warm up PLA or PETG prints to adjust tolerances or reshape them for special applications.

Silica gel drying – regenerate silica gel packs easily by placing them on the elevated platform.

⚠ Always print this mod in a heat-resistant material to avoid deformation of the structure itself.

Recommended materials:

Prusament PCCF Blend

Polymaker HT-PLA

Other high-temperature composites (avoid nylon, as it tends to warp under constant pressure).
